Purdue, Wichita State partner for analysis

That’s the result published in the 2013 Airline Quality Ratings report released Monday, reports CNN.

The report — which covers the 14 largest U.S. airlines — is produced as a joint venture between professors at Purdue University and Wichita State. The researchers used data from the U.S. Department of Transportation to measure airline performance in on-time, consumer complaints, lost luggage and denied boarding events.

Southwest (NYSE:LUV) had the lowest level of customer complaints while giant United Air Lines (NYSE:UAL) had the highest at 4.24 complaints per 100,000 passengers. Virgin America had the lowest rate of lost or damaged luggage and American Eagle (PINK:AAMRQ) had the highest.
